Research indicates that microleakage is the major cause of composite restoration failure. Because the different physical properties of composite resin and tooth structure cause microleakage in composite tooth restorations, it is possible to eliminate microleakage by making composite's physical properties more similar to those of tooth structure. This article reviews the physical properties of composite resin systems last as they relate to tooth structure and microleakage.
研究表明，微渗漏是复合树脂修复失败的主要原因。由于复合树脂与牙齿结构的物理性质不同，导致复合树脂牙齿修复中出现微渗漏，因此可以通过使复合树脂的物理性质更接近牙齿结构的物理性质来消除微渗漏。本文综述了复合树脂体系的物理性质，以及它们与牙齿结构和微渗漏的关系。
